Receive UDP messages in non-blocking mode with waitformultipleobjects

See more:

sockets

I have two programs that are client/server pairs and they use UDP to talk to one another. In 'What have you tried' is an example of what the server is doing to receive requests from the client. The "stop" message is sent by clicking a button on the server's window while the recvfrom loop is running in a background thread.

On another project I am using WaitForMultipleObjects and I'm thinking I should change my UDP server to use it. Instead of sending a message "stop" to itself, I could use an event to signal WaitForMultipleObjects and check the return code to see if the event was signaled or data came in.

I haven't been able to find a good example of what I need to change in my Winsock code.

I would appreciate any good suggestions.

What I have tried:

RecvSocket = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP)

StructSize = 16
RecvAddr4.sin_family = AF_INET
RecvAddr4.sin_port = htons(aui_port)

iResult = bind(RecvSocket, RecvAddr4, StructSize)

do while true
   bytesrecvd = recvfrom(RecvSocket, recvbuf, &
                bufsize, 0, RecvAddr4, StructSize)
   if recvbuf = "stop" then
      exit
   else
      ' do something with the data
   end if
loop
